I beleive I will go the safest way since electrical issues with the X5 are a costly pain.

Why take the risk. Common sense says electricity, wires, and water is not a healthy mix for your investment.

I think i will go the old fashioned tedious way of spray and wipe clean, then dress it up after. When the weather clears this will be my Sat project.
Will take pics when i dig out from 12 inches of snow first.
